12" Wooden Ruler made in U.S.A. of American-grown basswood. We took a slightly different approach when putting this ruler together, and the result is an extremely interesting list! Instead of starting with a list of people that we wanted to consider, we chose to start with the National Parks that we wanted to highlight, and then found people who were significantly affiliated with that park. The dates listed are the year in which each National Park was established, and the order of entries is by that year. The “head” image is that of president Theodore “Teddy” Roosevelt, often called the conservationist president, who during his presidency created the United States Forest Service and established 5 National Parks, 18 National Monuments, 150 National Forests, the first 51 federal bird reserves, and 4 national game preserves.
